Essentially the Missal of St. Pius V is the Gregorian Sacramentary; that again is formed from the Gelasian book which depends on the Leonine collection. We find the prayers of our Canon in the treatise “De Sacramentis” and allusions to it in the 4th century. So our Mass goes back, without essential change, to the age when it first developed out of the oldest liturgy of all. It is still redolent of that liturgy, of the days when Caesar ruled the world and thought he could stamp out the faith of Christ, when our fathers met together before dawn and sang a hymn to Christ as to a God. The final result of our enquiry is that, in spite of unsolved problems, in spite of later changes, there is not in Christendom another rite so venerable as ours.
— Fr. Adrian Fortescue (d. 1923)

OOKING AT MUSIC on the page is one thing, but hearing it real life is a different matter. I’ll never forget hearing Dr. Alfred Calabrese run through Guerrero’s KYRIE on the opening day of our very first Sacred Music Symposium. As a composer, I was in awe of what Guerrero had done: his grasp of musical DENSITY was life-changing. (No recording can capture this.)

These composers were aware of the overtone series, which is sometimes described as a series of “imaginary notes.” Let us consider an AGNUS DEI by Guerrero’s teacher, Fr. Cristóbal de Morales. The following recording—which I consider to be quite beautiful, especially for those familiar with this piece—was created by members of the volunteer choir I direct here at FSSP.la.

In measure 38, Tenors combine into unison on C—do you hear an imaginary girl’s voice singing a high G? (That’s a strong overtone.) Listen to the 1:31 marker:

THEFRATERNITY OF SAINT PETER in Los Angeles released a Promo Video celebrating the 10-year anniversary of “Summorum Pontificum.” The recording above was chosen as the soundtrack, and here’s a translation for the Chanson which Fr. Morales used as his melodic basis for Missa Mille Regretz:

English Translation:
A thousand regrets at deserting you
and leaving behind your loving face,
I feel so much sadness
and such painful distress,
that it seems to me my days
will soon dwindle away.

It’s fitting, in a way, because many priests I’ve asked about the 1960s reforms have expressed regret. When they opened up the new Missal for the first time (they explain) they saw that much of the beautiful symbolism and holy gestures of the ancient liturgy had been eliminated. As one bishop put it, “I knew it was gone for good.” Nobody at that time could have even hoped for something like “Summorum Pontificum.”
